INVENTOR HARRY B. LEWIS Patented Oct. 13, 11931 UNITED -STATES PATENT OFFICE HARRY B. LEWIS, OF BROOKLYN, NEW YORK, ASSIGNOR'TO BOORUM & PEASE COMPANY, F BROOKLYN, NEW YORK, A CORPORATION 0F NEWl YORK Loosn LEAF RING Boox Application led November 23, 1929. Seria1`No. 409,395.

This invention relates to loose leaf ring books and more particularly `to those having a plurality vof rings which are complete and pass loosely through the two covers of the book. It has been discovered that with this type of book the various rings are apt to turn longitudinally of the back of the book at various angles relative to each other which makes it hard to open the book or to turn the sheets in the book when it is opened. The object of this invention is to insure that the rings will always lie in parallel planeslthus making it possible at all times to turn the sheets or cards in the book from one side to the other of the book without jammingor In the drawings:

Figure 1 is a side elevation' of a closed loose leaf ring book embodying vthe invention.

Figure 2 is a vertical section of the book shown in Figure `v1 on a line corresponding to 2-2, but showing the book opened and showing in rdotted lines one leaf being turned from one side of the book to the other.

rlhe ordinary loose leaf ring book consists Vo f-two covers 7, having openings 8 in one longitudinal edge thereof to receive rings 9,

which are otherwise completely free or detached from said covers. The sheets 10 in z the binder are threadedv on these rings 9, the

rings being hinged for this purpose. It will be noticed that with this ordinary construction the rings can flop in opposite directions and that when the binder is open this Hopping will vary the distance between the rings at the points where they pass through the sheets, thus causing the sheets to be torn or jammed if an attempt is made to turn the sheet from lone side to the other.

This tearing or jamming effect is particularly undesirable when the covers of the ring boo are turned apart with an angle of less than 180 between them, to lform a stand, and the sheets are moved over the rings through less than 90 between their outer sides. The

degree, the novel member 14 occupying only Such a positionis shownI covers are held at this angle by a chain -11 which may be permanently attached'to ,to consult various charts mounted on cards actin as leaves. For example, it may be used y gasoline filling stations when greasing a car, there being a chart for each make of car.

In order to avoid the contlicting movement of the rings, a rigid element 14`is provided at the back of the binder outside the two covers through which the rings can be threaded. The holes 15 in the rigid element through which the rings pass are preferably made a rather close t for'the latter. The rigid member 14 is shown in the drawings in the form of a strip or bar. It is movable longitudinally at the back of the binder, i. e. relatively to the covers as shown at 14a in Fig. 1 of; the drawings. By thus giving eachA ring three points of support i. e. one on each cover and one on the bar, and making each of these points of support movable independently in a direction longitudinally of the back of the-book, the rings are given all the freedom that is desired and yet arevalways kept in parallel planes. With this construction it will be obvious that the sheets or cards can be turned' over from one side to another of the binder when set inthe form of a rack as shown in Figure 2 without 'amming the sheets on the rings. In that gure a sheet 10a is shown being turned from one side of the rack to the other. It will also be noted that the book can be opened to any desired a negligible amount of space and permitting the rings to pass through it as desired.

' What I claim is:

1. A loose leaf ring book having two covers, a vplurality of free rings passing therethrough and a member outside the two covers through which said lrings'pass ypermitting said rings to flop but malntaining them in parallel planes. y

2. A loose leaf ring book comprising a 100 plurality of coversz a plurality of free rings passmg through said covers and a bar lying .outside said covers, said rings passing through said bar,.said bar being movable longitudinally of the back of the ok.

3. A loose leaf ring book comprising a pair of cover-s, two or more free rings passing through said covers and a member eX- tending longitudinally of the back of the book onthe outside thereof through 'which said rings pass, adapted to maintain said rings Iin parallel lanes, said member being movable longitudinally of the backof the book and means on said covers to hold same in open position at an angle-of less than between the outer sides thereof.

In testimony whereof l have signed my name to this specification.

HARRY B. LEWIS.
